BMW 5 Series
The 2014 BMW 5 Series is made up of sedans and hatchbacks that feature no fewer than six different drivetrains, including a new diesel engine in the 535d sedan. It’s a 3.0L 313-hp in-line six-cylinder twin-turbo engine. At the other end of the spectrum, the powerful M5 sedan remains true to its 4.4L 560-hp V8 turbo.
